Power Mirrors



Diagnosis & Testing

If the power mirror system fuse is open and a short to ground in the battery positive voltage circuit is not detected, the fault could be a short to ground in one of the power mirror control circuits. This would open the power mirror system fuse when the mirror switch is pressed.

If both power mirrors are inoperative on one or more axis, the most probable cause is a power mirror switch failure. However the fault could be an open circuit on two or more of the power mirror control circuits.

The power mirror assembly is equipped with a pigtail harness and is not serviceable. If an internal open or short is detected in the power mirror assembly, replace the power mirror assembly

  1. Disconnect the appropriate power mirror.
  2.  
  3. Connect a test lamp between the appropriate mirror motor control circuits of the power mirror harness connector.
  4.  
  5. Place the mirror selector switch to the mirror to be tested.
  6.  
  7. Activate the power mirror switch in both directions for the functions being tested. If the test lamp does not illuminate in both directions, the motor must be tested.
  8.  
  9. Test the mirror motor control circuits for an open.

  11. Inspect for poor connections at the harness connector of the power mirror switch.
